GAGE ATTACHMENT FOR FASTENER-SETTING MACHINES.

SPECIFICATION formingpart of Letters-Patent No. 645,938, dated March 27,1900.

Application filed January 5, 1900. Serial No. 415. (N0 model.)

To all whom it may concern:

Be it known that I, GEORGE W. BROWN, of Quincy, in the county of Norfolkand State of Massachusetts,have invented certain new and usefulImprovements in Gage Attachments for Lacing-Stud-Setting Machines, ofwhich the following, taken in connection with the accompanying drawings,is a specification.

-My invention relates to a gage attachment to lacing-stud-settingmachines; and it consists in certain novel features of construction,arrangement, and combination of parts,which will be readily understoodby reference to the description of .the accompanying drawings and to theclaims hereto appended and in which my invention is clearly pointed out.

Figure 1 of thedrawings is a front elevation of my gage attachment shownin full lines and showing in dotted lines so much of a stud-settingmachine as is necessary toillustrate how said attachment is applied tothe machine. Fig. 2 is a plan of the gage attachment. Fig. 3 is an endelevation looking at the right-hand end of Fig.1 with milled studremoved; Fig. 4=is a'sectional elevation, the cutting-plane being online00 on on Fig. 2 and looking toward theleft of said figure. Figs. 5 and 6are inside elevations of portions of the right and left quarters of aboot in which studs are to be set.

In the drawings, 1 represents the frame of the head of a powerstud-setting machine; 2, the spindle which carries the clenching-anvil3. at is the raceway along which the studs are conveyed from thereservoir 5 to the pocket in the upper endof the reciprocating plunger6, all of which parts are constructed, arranged, and operatesubstantially as shown and described in the Letters Patent No. 27 7,965,issued to WVilliam O. Bray May 22, 1883.

The object of my invention is to provide a gage that may be readily andaccurately adjusted to the proper position for determining the properdistance from the top of the bootquarter for setting the first stud,which in the right quarter is the stud nearest the top of the boot andin the left quarter is the stud farthest from the top of the boot; also,to determining the distance from the meeting edges of 'said quarters forsetting all of said studs, and also to aid the operators eye in other.

determining the distance between two studs, and to this end I providethe angularly-bent bar 7, havinga long and a short arm, to the short armof which, near the bend of said bar, 5 5 is secured in a fixed positionby the screws 8 the angular plate 9, the two arms of which are at rightangles to each other, to the horizontal arm of which is adj ustablysecured the plate 10 by means of the screw 11, screwing 6o into theplate 9 after passing through the'slot 12, formed in said plate 10, saidplate 10 being provided with the downwardly-projecting lips 13, whichembrace the edges of the horizontal arm of the plate'9 to prevent anyswiveling action of said plates 9 and 10 upon each The plate 10 hasformed therein a circular hole 14 to receive the shank of theclenching-anvil 3, the shoulder on whichbears against the under side ofsaid plate 10 and 7'0 clamps it between said shoulder and the lower endof the spindle 2 to hold said bar 7 in the desired position, with itsshort arm substantially at a right angle to a vertical plane drawnthrough the center of the setting-tools and the lower or terminalportion of the raceway 4. t

The short arm of the bar 7 has riveted or otherwise secured to its backside the stand 15, having at each end a rearwardly-projecting ear, inbearings in which is mounted so as to be revoluble and movable endwisetherein the spindle16, having secured thereon or formed in one piecetherewith the milled knoblike head 17 and has firmly secured thereon ina'fixed position between the ears of the stand 15 the four-sided block18, having a length somewhat less than the distance between the positeend of the block 18 and the opposite ear of the stand 15 the spindle 16has mounted thereon the coiled spring 21, the tension of which tends tohold said block in its locked The long arm of said bar 7 has theposition.

stand 22, constructed, arranged, and operating precisely like the stand15, except that it is longer secured thereto, as shown, and said stand22 has mounted in bearings therein the spindle 23, provided with thehead 24 and carrying the block 25, provided with four locking-pins, andthe spring 26, all constructed and arranged in the same manner as thesimilar parts on the other end of said bar 7. A gage 27, made from sheetmetal by bending the gage proper at a right angle to its shank orsupporting portion, is adjustably secured to said bar 7 by being clampedbetween said bar and the vertical portion of the angular plate 9 by thescrews 8, which pass through the slot 28 in the shank of said gage, asshown in Fig. 1. The short arm of the bar 7 has adjust-ably mountedthereon the clip 29, from one end of which projects the gage-plate 30, aportion 31 of which is bent into a horizontal position and the extremeend portion 32 of which is bent downward into a perpendicular positionand is the gage proper for determining the distance between any twostuds. This gage and its clip are secured in their adjusted positions bythe set-screw 33.

The long arm of the bar 7 has adjustably secured thereon the gage 34,which is formed in one piece with the clip 35, which is secured in thedesired adjusted position on said bar by the set-screw 36.

The upper edge of the clip 29 has formed therein the index-mark 37, andthe clip 35 has a similar index-mark 38 formed on its upper edge, asshown in Fig. 2.

The blocks 18 and 25 are preferably made 70f wood and have their sidescovered with white paper, upon which are marked aseries ofgraduation-marks indicating the several sizes from 5 to 10, inclusive,as shown. Each of the four sides of each of the blocks 18 and 25 mayhave such a series of graduation-marks placed thereon, one side of eachblock being marked for mens sizes, another for youths sizes, another forboys sizes,and another-the little gents sizes.

The operation of my invention is as follows: The blocks 18 and 25 beingcovered with fresh paper without marks of any kind thereon and placed inposition in the stands 15 and 22, if a case of mens boots are to besupplied with lacing-studs and the manufacturer requires the upper studto be at a given distance, say one-half inch from the top of thequarter, the gage 27is adjusted to that distance from the center of theclenching-anvil, and the bar 7 and the vertical portion of thegage-plate 9 are so adjusted on the plate 10 that the front face of theplate 9 shall be at the desired distance from the center of said anvil,and the clip 29 is adjusted upon the bar 7 to bring the gage-point 32 ata distance from the center of said anvil equal to the required distancebetween two adjacent studs when set, say, on a No. 5 boot. \Vhen theclip 29 is firmly secured in position, a mark No. 5 is made on the papercover on the face of the block 18 that is inclined toward the front andalso other marks 6, 7, 8, 9, and 1O at such distances from each other asare due to the required varying distances between two adjacent studs inthe different sizes of boots. The operator then places the quarter 39, aportion of which is shown in Fig. 5, beneath the anvil 3, with the end40 thereof in line with the gage 27 and the edge 41 in contact with thevertical portion of the angular plate 9, with the inside of the quarterupward, and sets the first stud at a. The quarter is then fed to theright until the center of the stud just set is beneath the gagepoint 32,when a second stud is set at I). Then the stock is fed till the point bis beneath the gage 32, and a third stud is set at c, and then anotherfeed takes place and the fourth stud is set at d.

The above paragraph applies to a No.5 boot. If any other size ofboot-quarter is to be operated upon, the clip 29 is adjusted till theindex-mark 37 is opposite the .mark on the block 18 indicating theappropriate size of boot, and the operation will be the same as abovedescribed.

As the work is always fed toward the right, when studs are to be set inthe quarter 42 (shown in Fig. 6) the stud farthest from the top end 43of said quarter must be set first. To determine the position of thefirst stud to beset in the quarter 42, aportion of which is shown inFig. 6, the, gage 34 and its clip 35 are adjusted on'the bar 7 to bringthe inner face of said gage at a distance from thecenter of the anvilequal to thedistance between the end 40 of the quarter 39 and the laststud set in said quarter. The several graduationmarks :4 u 4c H8, 97 andu 107, are then made on ,the side of the paper-covered block 25 which isinclined toward the front, with the mark 5 opposite the index-mark 38 onthe clip 35 and with the other graduation-marks at the proper distancesfrom said mark 5 toward the left thereof,corresponding to the requireddistances between the top of the quarter andthe center of the studfarthest from said top of the quarter, due to the variations in thedifferent sizes. The operator then takes the quarter 42, places itbeneath the anvil 3, with its top 43 against the gage 34 and its edge 44in contact with the vertical portion of the plate 9, and sets the firststud at e. The work is then fed to the right until the center of thestud just set is beneath the gage-point 32, and the second stud is setatf, and in like manner the work is fed and studs set at g and h insuccession, the stud set at It being the same distance from the top 43of the quarter 42 that the stud The drawings of the boot-quarter shownindicate that only four studs are to be set in each quarter; but it isobvious that more or less than four studs may be set in each quarter andthe blocks 18 and 25 for one or more additional sizes, if desired.

If youths, boys, or little gents sizes are to be operated upon, theblocks 18 and 25 are partially rotated to bring a fresh unmarked side tothe front, when the operations above described in relation to mens sizesare repeated.

To change the blocks 18 and 25 so as to bring a different side thereofinto-a position inclined toward the front, the block is moved endwiseagainst the tension of the spring 21 or 26, as the case may be, bypressing upon the head 17 or 24 to unlock said block, which is thenpartially rotated until the desired side is inclined toward the front,when the pressure being removed from the head the spring 21 or 26 willagain cause the block to be tacked in said new position.

What I claim as new, and desire to secure by Letters Patent of theUnited States-, is-

l. A gage attachment for stud-setting machines comprising asupporting-plate constructed and arranged to embrace and be clamped tothe clenching-anvil of said ma-' chine; a pendent gage-plate todetermine the distance from the meeting edges of the bootquarter atwhich the lacing-studs shall be set, said gage-plate being mounted atthe rear of said anvil and adjustable to a greater or less distancetherefrom; a gage-carrying bar secured, between its two ends, to saidsupporting-plate, at the rear of said anvil, and adjustable to a greateror less distance therefrom toward the rear; a gage adj ustably mountedupon said bar at the right of said anvil for determining the distancefrom the top of the right boot-quarter for setting the upper stud; agage adjustably mounted upon said bar at the left of said anvil, fordetermining the distance from the top of the left quarter for settingthe lowermost stud; and another gage adjustably mounted upon said bar atthe right of said anvil for determining the distance between twoadjacent studs in either of the boot-quarters.
